Abstract: PURPOSE:To decrease the deterioration in the S/N of the entire circuit by controlling the resistance value of a variable resistive element inserted in series with the base of an input stage amplification transistor (TR) in a variable gain amplifier circuit used for a reception intermediate frequency amplifier so as to control the circuit gain. CONSTITUTION:In changing the resistance value of the variable resistive element 20 provided in parallel with a feedback resistor 8, the negative feedback amount of a negative feedback circuit is changed and the gain of the amplifier circuit viewed from a base terminal (c) of a TR1 is changed. In the control to decrease remarkably the overall gain while a high input level signal is inputted to an input terminal (a), the resistance value of the variable resistive element 20 is reduced and the gain of the circuit viewed from the output terminal (b) is decreased. Even when the resistance value of the variable resistive element 4 connected to the input side is comparatively small, it is possible to attain a required gain reduction. Since the loss of the variable resistive element 4 at the input side is suppressed lower, the S/N is deteriorated largely even at a low gain.
